You wouldn't have to share private RL stuff with us. The idea is to at least post some information on how you play, how you heard of this site, etc, forging that into an introduction.
I don't know what your health issues are, but I can GUARANTEE you that there are people here who have some VERY SERIOUS health issues themselves, and still find the time/health/whatever to write entire scripts to be shared here with the entire community. And very useful scripts at that.
So yeah, if you really appreciate the "hard (work) that has been done", my guess is you could at least put together a few sentences to form a somewhat acceptable introduction, to show us that you at least care a little bit about other people who have worked hard in putting up a great website for you and so many others without asking anything in return (except for the intro?).
Good luck with your health!
